The PML differential covers are a welcome alternative for those who are looking for the added benefits of increased cooling and a magnetic drain plug, but at a lower cost than other brands. Cast in unfinished aluminum, and the additional cooling fins, PML differential covers provide exceptional cooling over stock covers. All covers have a flat boss that can be drilled and tapped for the use of a temperature gauge sender.

PML designed this differential cover for the American Axle rear end on Duramax trucks with the Allison transmission. The cover has space at the top and includes longer bolts for the brake bracket. The differential cover has oil fill/level check hole and a drain hole with a magnetic plug to facilitate oil changes. If you have an oversized spare tire, you may need to move the tire towards the rear. There is tube that holds the spare tire in place and the position can be easily adjusted.
